public class NativeArrayBuffer
extends ScriptableObject

A NativeArrayBuffer is the backing buffer for a typed array. Used inside JavaScript code, it implements the ArrayBuffer interface. Used directly from Java, it simply holds a byte array.

byteOrder

Constructor Details

NativeArrayBuffer

public NativeArrayBuffer()

Create an empty buffer.

NativeArrayBuffer

public NativeArrayBuffer(double len)

Create a buffer of the specified length in bytes.

Method Details

getClassName

public String getClassName()

Description copied from class: ScriptableObject

Return the name of the class.

This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

init

public static Object init(Context cx,
 VarScope scope,
 boolean sealed)

getLength

public int getLength()

Get the number of bytes in the buffer.

getBuffer

@Deprecated
public byte[] getBuffer()

Deprecated.

This method will return null for shared buffers and possibly other buffers in the future. Callers should use getByteBuffer() instead.

Return the actual bytes that back the buffer. This is a reference to the real buffer, so changes to bytes here will be reflected in the actual object and all its views. In the future, for a shared array buffer this will return null -- callers should use getByteBuffer() instead.

getByteBuffer

public ByteBuffer getByteBuffer()

Return a buffer that points to the contents. The position will be zero and the limit will be the length of the buffer. The buffer is returned using Buffer.duplicate().

detach

public void detach()

isDetached

public boolean isDetached()

isResizable

public boolean isResizable()

Return true if this ArrayBuffer is resizable (ES2024).
